SANTA CLARA -- Sunday morning's earthquake 75 miles north of Levi's Stadium hasn't impacted the 49ers exhibition against the San Diego Chargers, outside of train cancellations from the East Bay.

The game remains on schedule for a 1 p.m. kickoff, and the 49ers announced that engineers will continue to inspect the $1.3 billion stadium throughout the day for any effect from the 6.0 earthquake centered in American Canyon near Napa.

Roughly 1,250 fans will have to make alternate plans to get to the game as a result of cancelled train service while rails are inspected for damage, impacting those who take the Altamont Commuter Express and Amtrak's Capital Corridor lines.

Three hours before kickfof, players began warming up on the field and were checking their footing on the sod that was installed on Friday. The former surface, Bandera Bermuda, was pulled up after Wednesday's abbreviated practice because the field conditions became perilous to players, several of whom slipped.

Here is a statement Sunday morning from the 49ers:

"We would like to extend our best wishes to all of our neighbors, family and friends affected by this morning's earthquake.

"Today's 49ers game at Levi's® Stadium will be played as scheduled.

"Levi's® Stadium was designed to meet California seismic code requirements and seismic bracing was incorporated into the design and construction. Building engineers have walked the entire stadium and we have had no reported damage. We will continue to do so throughout the day.

"In terms of trains servicing the stadium, we have been advised that all tracks have been shut down within a 100-mile radius of Napa until further notice, therefore affecting the ACE and Capital Corridor service to the stadium. ACE would normally carry upwards of 500 passengers to our game. Capital Corridor carries approximately 750 fans. We remain in communication with these agencies. Caltrain and VTA are operating as scheduled at this time."
